Excuse my Ingorance man, but Im sure you could do alot of for a bit cheaper.. Such as the brakes,Gemini or piazza diff, and the piazza fronts with a gemini master cylinder and your sorted , all up for less than $200 (complete car, brakes & gearbox..)  And a gearbox depending on what you get.. Theres a joker down here thats got 3 Gearbox's for sale on trademe, x4spds, and one 5spd Piazza box, $70 for the lot... Cheers,Chris |

I need to use a 4 cylinder VN commodore box, of which I can score a mint 100 kilometre one for $200 with driveshaft. I already have Piazza brakes, but I am looking at something a little more up to the task - possibly zeps. The piazza's aren't bad and I would stand by them, but they don't age well and seem prone to fade under heavy use. The single piston calipers are also known to bind up aparantly. Thirdly lol  , I am anti torque tubes. They work fine for standardish cars, but in my opinion they aren't worth the cost of changing the panhard rod mounting point for lowered, track based cars. I'll just be sticking with a standard welded diff to get me going, then move up to something a little more modern. Cheers for the feedback, gets me thinking about how I should go about things. I probably should have mentioned that this is a VERY generously priced out list and I'm actually expecting it to come in under budget, but conversions are tricky and pricy monsters, especially when they aren't carried out commonly - such as this one. |

wobbley cams  Ooooo, I like your way of thinking. I'm real keen but I've heard that any more lift involves needing to cut slots into the pistons, cupping I think its called. Needless to say, if I do need to rebuild the engine I find, I will certainly look into longer duration cams and a nicely raised CR ;D |

Ah you mean fly cut pistons. You may need this, or you may not. It will depend on how far your valves go down now, and how low your pistons sit in the bores. I would maybe look into importing some after maket pistons from the UK?

Oh yeah, foriegn chaps seem to use different terms maybe? Thats good to know if I do need to get it done though. They say any increase in lift of the valves will require fly cutting and you can get away with removing 2mm from the pistons, which sounds like quite alot to me. But yeah, if I do go ahead with that then I'll also look into some pretty high comp, fly cut pistons from the UK as leon suggested. Things are a little pricy from over there, but we'll see what happens if it comes to that. They have some beautiful gear.

Just a thought, those 4cyl VN motor's, are they the same as the 4cyl VK motor's abeit with fuel injection, cause people basically give those away...
Cheers,Chris

As far as I'm aware they're not. I think the vk engines are short 186/202's, while the vn engine is a family 2 opel engine. Good thinking though, I was wondering the same thing ;D

Ah yes, I stand to be corrected, I thought they were Opel Motors , but no , you are right they are a 4cyl Version of the 6 cyl. "Starfire"

Good thinking though, I was wondering the same thing ;D Yeah i remember reading about how they took the worst engine ever and made it worse by choping off two cylinders ;D Can also get em with L20 nissan engines i think...maybe vl or vh. Mate had one in his car i think |

Nope 4 cylinder im thinkin of. Im sure he said it was an L20 or L18. But that wouldnt make sense now would it..... drugs surely must of been involved here
edit- i remember now! i had a dream and he was telling me how his comodore had an L20. And then we were gona put the L28 race engine(which my other friend has under his house) into it. Thats right cos his car def had one of those crazy holden 4 cylinders or somenuts. Yeah crazy nuts....

Finally got my engine underway last night. I went in on monday, which was nearly a full month after the date my car was initially booked in, and the engines were still in their complete state  I expressed my concerns to the manager of the business and he agreed that I will see progress the very next day. I went in yesterday after work to find the engines still complete but in a different spot. He suggested that I go on at 7pm after dinner and we'll strip the engines and get the project underway, which I was very happy with. So at 7 I went to the shop and we got underway. By 9 we had the twincam stripped back to a block and began on the 8v engine. By 10 this was in pieces and we began putting everything back together with the combination of the two. We weren't going fast by any means, just checking over the differences between various parts and seeing what part numbers matched and what didn't. It was very a interesting little task and I was very pleased with the results. We finished around midnight with a twincam head mounted on top of the 8 valve block with all the pulleys and cambelt in place and a VN commodore gearbox hanging off the back end. Everything is only dummied up at this stage to check compatibilty of parts and make sure the whole thing actually squeezes into my little car, but so far everything is looking great! The guys are still flatout getting rid of other cars to make room for mine in the shop so I won't be able to get in there until early next week. Thats abit of a pitty as track day is creaping up awefully fast now. Other than that I have bought a link G3 and I'm weighing up going with 4age 20v throttles and injection, but I do still like the idea of carbs so I think we'll still go with that. It suits the conversion better. Why do anything normal?
